The RT8207L/M provides a complete power supply for both DDRII/DDRIII/Low-Power DDRIII/DDRIV memory systems. It integrates a synchronous PWM buck controller with a 1.5A sink/source tracking linear regulator and buffered low noise reference.The PWM controller provides the high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high voltage batteries to generate low voltage chipset RAM supplies in notebook computers. The constant-on-time PWM control scheme handles wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency.
